1000W tire regroover: This portable regrooving machine uses resistance heating to recut tires on trucks and tractors. Ideal for solid tires and rubber products, it extends tire life through precise groove cutting. Stable DC performance: Features micro-computer temperature control for accurate heat management. Converts AC to DC power to enhance transmission, maintain lower working temperatures, and reduce energy loss with soft-start current. Safe intelligent control: Requires manual compression to activate heating, preventing accidental ignition. Adjustable power allows gradual temperature control. Built-in vents, fan, and LED indicator with energy-saving DC ensure safe use. 20 versatile blades: Includes 20 U/V/linear blades for cutting 2-14mm wide and 9-14mm deep grooves. Optimized for racing, truck, and industrial tires without overheating thanks to stable DC power delivery. Multi-tire compatibility: Works on ATV, motorcycle, go-kart, and commercial tires. Low-heat DC technology protects rubber during regrooving, maximizing pattern depth safely for all tire types.
